Just hours ago, SpaceX successfully launched its second batch of 60 Starlink satellites, featuring a variety of upgrades as part of the move from v0.9 to v1.0 spacecraft. During SpaceX’s launch webcast, the hosts revealed a number of intriguing new details about those upgrades, shedding a bit more light on what exactly has changed.

SpaceX launched its first dedicated Starlink mission in May 2019, placing 60 “v0.9” satellites in low Earth orbit (LEO) in what was essentially a beta test at an unprecedented scale. At the time, SpaceX and CEO Elon Musk disseminated a substantial amount of information, essentially taking the veil off of (part of) the company’s Starlink satellite program. In terms of the basics, Starlink v0.9 satellites were said to weigh approximately ~225 kg (500 lb) apiece, although the final mass – said to be the heaviest payload SpaceX had ever launched – suggested that that figure excluded the mass of krypton propellant.

All told, Musk said that the payload weighed ~18.5 tons but never clarified whether that was in imperial or metric units, leaving a potential range of 16,700-18,500 kilograms (36,800-40,800 pounds). In general, Musk was quite confident that SpaceX’s custom-built phased array antennas were effectively the best in the world even in their v0.9 beta-test iteration. Additionally, he noted that inter-satellite optical (i.e. laser) links would have to wait a generation or two before becoming part of the operational constellation.

Ch-ch-ch-changes

With SpaceX’s Starlink-1 launch, the second 60-satellite mission, the company debuted Starlink ‘v1.0’ satellites with a range of changes and upgrades that fall under two main categories: structures and communications.

Prior to the November 11th webcast, SpaceX’s official pre-launch press kit was far less revealing than Starlink v0.9’s but did note that v1.0 satellites have been upgraded to be “100% demisable”. This means that when each spacecraft reenters Earth’s atmosphere, everything down to the last shred of mylar is now expected to burn up before reaching the ground, reducing the (already miniscule) risk of debris harming people or property. Similarly, SpaceX implied several months before launch that v1.0 spacecraft would include tweaks to limit their reflectiveness after the astronomy community stoked fears about potential impacts.

Aside from a general improvement to the overall visual fit-and-finish of the v1.0 spacecraft, SpaceX’s official comments on the matter indicated that the most substantial changes between v0.9 and v1.0 were more related to each spacecraft’s advanced electronics and payloads. In the case of Starlink, each satellite’s primary payload is a high-performance suite of electronically-steered phased array antennas. Initially developed to improve the flexibility of tracking and scanning radars used by military fighter aircraft, phased array antennas (and radar) allow multiple beams to be aimed without physically moving the antenna.

SpaceX says that Starlink v1.0 satellites added a number of Ka-band antennas alongside upgraded Ku-band hardware similar to what was installed on Starlink v0.9. Ka and Ku refer to similar but different communications frequencies, with Ku-band generally offering greater reliability and cloud/rain tolerance, while Ka-band is a bit more sensitive to environmental factors but offers a substantially higher theoretical bandwidth.

According to SpaceX engineers speaking during the Starlink-1 launch webcast, Starlink v1.0 satellites offer an unexpected 400% increase in overall bandwidth, meaning they can theoretically transmit four times as much data per any given second. Additionally, Starlink v1.0 satellites were said to feature antennas with twice as many steerable beams, meaning that they can effectively serve two times as many regions simultaneously. It’s unclear if the addition of Ka-band antennas is the sole source of these substantial improvements.

Furthermore, during the Starlink v0.9 launch, SpaceX CEO Elon Musk indicated that the 60 satellites represented a bandwidth of more than 1 terabit per second (Tbps), translating to ~17 Gbps per satellite. More likely than not, Musk was speaking aspirational and the v0.9 satellites actually represented more like ~200-300 Gbps worth of throughput, with the additional of Ka-band antennas and perhaps general technology upgrades bringing v1.0 satellites to a nominal ~17 Gbps apiece.

For now, 60 Starlink v1.0 satellites are now in orbit and are rapidly spreading out after their bizarre but effective blob-style deployment. With any luck, all 60 will successfully deploy their solar arrays and begin propelling themselves towards their final operating orbits with krypton-fueled ion thrusters. Stay tuned for updates from SpaceX!

Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990

Published

on

Tesla has officially launched the Model Y L in the United States and Puerto Rico for $61,990. It is the longer-wheelbase version of the Model Y, and has been available in China since last year.

Tesla brings the Model Y L to the U.S. just months after it phased out the only pure SUV in its lineup, the Model X. It is slightly longer than the Model Y configurations that are already available in the U.S., and features a three-row, six-seat setup with Captain’s Chairs being among the many features that make this a truly fantastic offering.

The Model Y L is priced competitively at $61,990, and features 325 miles of range and a 0-60 MPH in just 4.4 seconds.

Tesla also added a handful of new features that are not available in even the Premium Model Y. Here’s a full list of its features:

  • Heated/Ventilated Front Seats with Powered Thigh Cushion
  • Heated/Ventilated Captain’s Seats in Second Row with Powered Armrests & One-Touch Fold
  • Heated Third-Row Seats with Power Recline, One-Touch Fold & Child Seat Anchors
  • Improved Airflow, Increased Efficiency, More Range
  • 89 cubic feet of trunk space
  • Upgraded Acoustic Glass and Suspension to Minimize Road Noise
  • Adaptive Damping for a Smooth, Stable Ride
  • Staggered Tires for Enhanced Grip
  • Larger Tailgate for Better Rear Visibility and Bigger Windows Overall
  • 16″ First Row and 8″ Second Row Touchscreens
  • 19-Speaker Immersive Tesla Audio
  • 50W Wireless Charging Pads with Active Cooling and Charging Ports for All Other Seats
  • FSD Supervised and Integrated Grok AI

Tesla is also delivering these first units as a “Launch Series,” which comes with additional features, such as:

  • Door Trim Puddle Lights
  • Suede Dashboard Wing
  • Exterior and Interior Badging
  • Floor Mats
  • Sill Plates

The launch of the Model Y L in the U.S. marks a huge offering from Tesla to U.S. consumers. People have been calling for Tesla to bring a larger car to the U.S., and it needed it more than ever now that the Model X is gone.

It is a huge accomplishment for Tesla to get the Model Y L to the U.S., and after reporting strong deliveries today, it will be interesting to see how this car impacts future quarterly delivery reports.

Deliveries for the Model Y L “Launch Series” are slated for September or October of this year.

Tesla just told us twice that Model Y L is coming to the U.S.

Tesla just told us twice that the Model Y L is coming to the U.S., and two social media posts definitely just tipped the company’s hand, as if they wanted it to be any other way.

The two social media posts basically confirm that the slightly longer version of the Model Y will be heading to the United States soon, and many have speculated that the company could launch the vehicle as soon as this weekend.

The first post was directly from Tesla, and it showed an incredibly long Dachshund, with words above that said, “Looking forward to the long weekend.”

Anyone who knows Tesla knows the company loves to troll its fans and have fun, and this is a perfect example of that. While not a direct acknowledgement, Tesla is very involved on social media, especially CEO Elon Musk’s platform X, and the company is well aware of what is being discussed within the community.

With recent sightings of Model Y L test mules in California, peeks of the vehicle at Giga Texas, and a large call for the car to come to the U.S., Tesla is simply stoking conversation with this.

However, the company also made another move that was recognized on social media. Tesla has a large gallery that includes photos of its products so media and others can use them. This gallery applies to the U.S. market specifically, unless otherwise specified.

Tesla uploaded a Model Y L to the Gallery last night:

This seems to be another indication that the Model Y L is coming to the United States.

Musk said last year that the Model Y L could make its way to the United States late this year, but it was not something that was set in stone by Tesla. The company definitely needs to establish something in the SUV market that is larger than the Model Y, and the Model Y L might be the answer.

Even still, there are consumers out there who would love Tesla to develop something even larger, like a competitor to the Tahoe or Expedition. Tesla has not really given much of an indication that it will go in that direction.

Tesla is using vehicle microphones to improve build quality: here’s how

Published

Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.

It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.

As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.

The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.

It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.

Tesla’s ‘megacasts’ are key to massive build quality improvements

While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.

This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.

Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.
